"""PLAN 322-3 측점 계획 한 벌 — 파이썬 `plan_stations` = TS `planStations`(거울) · 서버 공급자가 같은 목록.

- 측점 = 표 횡단도(anchor 기준 · span3 시작 · 기준 · 끝 · none 없음) · 카드 이름 = 표 카드 이름.
- 같은 m(0.005) 는 하나 — 이름 = 관이 먼저 · 아니면 앞선 것 · 덮는 구조물 id 모두.
- 빈칸 경고 = 형상 부품 필수 칸 중 값이 빈 것(관경 · 벽 높이 · 맹암거 높이 · 물넘이 높이).
- 서버 `resolve_extra_stations` = 계획의 (측점, 이름) — 겹친 자리는 한 번(옛 「마지막 이름」 규칙 걷음).
TS 쪽 = `helper_322_3_plan.cjs`(Node).
